-M3919, 1931 I I H. RESCH TYPEWRITING MACHINE Filed Nov. 19; 1925 Patented May 19, 1931 v UNITED STATES PATENT FFICE HENRY BESCH, F BAYONNE, NEW JERSEY, ASSIGNOlB. TO UNDERWOOD ELLIOTT FISHER COMPANY. OF NEW YORK, N. Y., A CORPORATION OF DELAWARE TYPEWRI'IING. MACHINE Application filed November 19, 1926. Serial No. 149,889.

This invention relates to an improvement in typewriting machines, and more especially to tabulating mechanism whereby the typewriter-carriage, which holds a worksheet divided into zones and subdivided into columns, can be tabulated to any column or subdivision thereof in each zone, or from a column in one zone to any selected column or subdivision thereof in an adjacent zone.

In the embodiment shown, a set of tabulating keys is used to control the jump movements of the carriage. These keys, hereinafter referred to as column-keys, are marked with designations for the respective columns within each zone of the work-sheet. Depression of a column-key will project a columnstop into the path of movement of a zonestop adjustable on the carriage with respect to a zone on the work-sheet, and the column stop will operate a carriage-release mechanismto release the carriage to move freely from the right to the left side of the machine until the movement is arrested by the zonestop striking the projected column-stop. The utility of the foregoing sequence of operations is apparent when considered in connection-with-the tabulation of the carriage of a typewriting machine in accordance with the bill-form or work-sheet illustrated. In this connection, and assuming that the carriage is at line-starting position, then by depressing a selected one of the column-keys, the carriage will be tabulated to the column in the first zone, as designated by the selected key. A second depression of the same key will tabulate the'carriage to a corresponding column in the second zone, and so on. en the carriage is tabulated to any selected column except the last column in any zone, further tabulation to any other selected column within the zone is accomplished by depressing the key marked with the designation for the selected column.

A feature of the resent invention resides in the provision o a special column-key, which may be arranged beyond one end of the set of'column-keys. When the special column-key is depressed, a key-lever is operate to lift a plunger, which operates thecarrlagerelease mechanism, shown and described in the patent to J. C. McLaughlin, dated April 26, 1910, N0. 956,144, and also operates an additional swingable stop, one end of which is provided with a finger, which, when swung upwardly, is projected across the path of movement of t e zone-stops The swingable stop has a limited amount of endwise movement, and moves with the carriage when struck by a zone-stop. A shock-absorbing device, which may be an ordinary retractile spring, is connected to the swingable stop and to a fixed part of the machine, and is efiective for restraining the movement of the additional stop to an extent sufiicient for absorbing the shock incident to arresting the movement of the carriage. The finger is set for a distance far in advanceof the set of column-stops, and is therefore effective when moved into contact with the column-stop housing for increasing the range of the tabulatingemechanism to the extent of the distance tween the finger and the next adjacent column-stop. In the present form of the invention, this distance is about the same as the distance between the respective column-stops or as the width of one of the columns, so that the special or additionalstop permits the use of zones, on the work-sheet or bill-form illustrated, wider than the set of column-stops.

Another feature of this invention relates to means for adjusting the position of the special stop relatively to the. standard parts of the machine, to the end that the device maybe easily fitted to any standard machine having a decimal tabulating stop mechanism. This adjustment may include an eccentric disk rotatably mounted on a fixed stud which serves also as a means for binding the disk in its set position.

Other features and advantages will hereinafter appear. 1

In the accompanying drawings, Figurel is a the invention app ied to a typewriting machine ,having a decimal tab ating mechanism.

Figure 5 is a diagrammatic view showmg the spec1al stop elevated for arresting the carriage.

Figure 6 is a diagrammatic view showing how the special stop clears the carriage when the operating key is released.

This invention is illustrated as applied to an Underwood ty writing machine having a dec mal tabulatmg stop mechanism. The machine has a traveling carria e provided at the rear thereof with a crossar 10, havlng teeth 11 for receiving adjustable zonestops 12. The carriage is also provided with a platen 13 rotatably mounted on a shaft 14, which platen, together with the feedrolls 15, serves as a means for holding and line-feeding a work-sheet 16.

The workheet 16, selected to illustrate one use of this invention, is provided with three zones of corresponding width and respectively indicated by 17, 18 and 19. Each of said zones is subdivided into four columns of corresponding width. When the character of the billing in connection with the use of said sheet is such that the use of the first column, designated by-the term Part in the respective zones, is not needed, the tabulation of the carriage may be effected by depressing the column-keys 24, which are re spectively marked with the designations A,

B, C, to correspond with the designations used for the columns in each of the zones.

Column-sto s 20 are mounted in a housing 21 which is ast to the framed the machine. The housin carries at thetop thereof a pair of slotte plates 22 which are fast thereto by means of screws 23. These plates serve as a means for guiding the upper ends of the stops 20 which are moved upwardly by depressin their respective keys 24, which are mounted at the ends of key-levers 25, pivotally mounted on a cross-bar 26.

The usual way of operating this machine, when all of the columns are to be used in one or more of the zones, is first to tabulate the carriage by depressing the special key 27 marked Part, which releases the carriage to tabulate to the Part column in the first zone of the work-sheet. The A key 24 adjacent the Part key is next depressed and the carriage is moved to a position to receive typing on the A column; and so on by operating the B and C keys. In case the entire first zone is to be jumped, the special key 27 is depressed for a second time and the carriage is automatically positioned for typing on the Part column of the second zone.

- The key-lever 28 of the special key 27 operates a plunger 20', which is made shorter than.

. stud 32 carried by the-front plate 22 The stop 31 is bent at one end thereof forming an interposing finger 33 which is disposed far in advance of the set of columnsstops 20 and is movable into the path of the zone-stops when the key 27 is depressed. The operation of the stop 31 is illustrated in Figures 2, 5 and 6. Figure 2 shows the stop in its normal position, while Figure 5 shows the stop afterthe special key is depressed to release the carriage, the movement of which is arrested by the finger 33. It will be noted, by referring to Figure'5, that the stop has been moved along with the carriage against the tension of a spring 34 into contact with housing 21, and the zone-stop 12 is spaced from the adjacent column-stop to an extent corresponding to the width of the first column in each zone. After releasing the key 27, the stop 31 is moved downwardly away from the tabulating stop and the spring 34 restores the plate again to its normal position as shown in Figure 6, with the finger 33 thereof arranged to the right of zone-stop 12. In order to relieve the special stop 31 from undue strain when struck by a zone-stop, it is proposed to make the spring 34 very heavy so that the same may act as a shock-absorber. The spring is mounted between the spring studs 37 and 38 respectively secured to the stop 31 and to one of the plates 22. The stop 31 is arranged so that,.when moved in the direction of the carriage, the finger 33 will strike the housing 21 as shown-in Figure 5.

This relieves the stud 32' from strain, since the shock is taken up by the housing.

The amount of engagement between the finger 33 and the tabulating stop may be adjusted by means of an eccentric disk 35 which passes through an elongated slot 36 in the stop 31. This disk may be positioned by loosening the stud 32 and by rotating the same therearound. Then the stud is tightened to lock the disk in itsset position.

Intermediate keys 39 are disposed between the column keys A-B, BC, and beyond the column-key C. These intermediate keys 39 are used for tabulating the carriage to select subdivisions of the columns A, B and C. Key-levers 40 are mounted on cross-bar 26, and are secured to the keys 39 and arranged for projecting intermediate stops 41,

which'are arranged in housing 21; the arrangement of column and intermediate stops is such that said stops provide a set of selected stops arranged at letter-space intervals.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
